Case Type   : cm_agent参数
Case Name   : 参数log_file_size功能验证
Create At   : 2025/3/27
Owner       : ningyali
Description :
    1.查询参数log_file_size默认值
    2.查看cm_agent下log个数
    3.修改参数值为1
    4.使用reload方式使其生效
    5.多次重启集群刷新大量日志
    6.查看cm_agent下log个数
Expect      :
    1.执行成功
    2.执行成功
    3.执行成功
    4.执行成功
    5.执行成功
    6.日志个数比第一次查看时个数变多
